While the maritime industry grapples with the transition to alternative fuels and evolving regulatory frameworks, the offshore sector faces its own decarbonisation pathway, one that shares common objectives but is shaped by fundamentally different operational realities.
The IMO’s greenhouse gas (GHG) strategy does not fully apply to offshore production units.
Offshore support vessels (OSVs), although required to comply, operate under different profiles from conventional deep-sea ships.
Offshore assets such as floating production storage and offloading units (FPSOs), floating storage and regasification units (FSRUs), drilling rigs and floating installations operate within diverse regional regulatory regimes, each imposing its own expectations on energy efficiency, emissions reduction and environmental performance, rather than a single global standard.
Requirements stemming from the EU MRV and ETS regimes, UK and Norwegian carbon taxation, Brazilian environmental licensing or emerging carbon-management rules in the Middle East create a highly fragmented compliance landscape.
For offshore operators, navigating this patchwork is an integral part of the decarbonisation challenge. While each region takes a different approach, all are moving toward commercially viable low-carbon offshore operations.
Equally distinct is the emissions profile of offshore units. Unlike deep-sea ships, where the majority of fuel consumption is dedicated to propulsion, offshore units generate emissions primarily from energy-intensive processes such as separation and compression.
OSVs, often operating in DP mode, depend on optimised power management and hybrid systems. For FPSOs, power generation systems can account for as much as 60% to 80% of total CO₂ output, while gas flaring continues to represent a significant 15% to 30%, followed by auxiliary equipment, such as pumps and compressors.
Reducing flaring, optimising power systems and adopting hybrid or carbon-capture solutions are the most effective ways to increase compliance and resilience.
Despite these challenges, the offshore sector has become an important proving ground for new technologies. Concentrated stakeholders, controlled operating environments and larger CAPEX budgets allow offshore units to adopt and test solutions earlier than deep-sea shipping.
Trials involving ammonia fuel cells, hybrid battery systems and carbon-capture modules have accelerated learning curves that the wider industry can benefit from.
Emerging technologies are also being deployed at the water-energy interface.
Floating wind and offshore renewable platforms draw on the offshore industry’s expertise in floating and mooring technologies, logistics and supply chains, with the long-term vision pointing toward integrated offshore energy hubs combining wind, CCS, ammonia and hydrogen, marking the next phase of maritime decarbonisation.
Offshore conversions, such as transforming LNG carriers into FSRUs or tankers into floating storage and offloading units (FSOs), are further bridging marine and offshore operations.
These projects demonstrate how adaptability, engineering precision and collaboration can repurpose existing assets into flexible components of a lower-carbon energy system.
At the same time, industry readiness remains uneven. While major Asian shipyards and European engineering firms are well prepared for green design integration, supply chains and regulatory frameworks for alternative-fuel infrastructure remain cautious.
Technical capability exists, but regulatory and economic uncertainty continues to constrain large-scale deployment.
Overall, the offshore sector’s experience underscores a broader lesson for the maritime transition: meaningful emissions reductions are achievable when innovation is matched with realism, regulatory engagement and operational expertise.
Early movers in regulatory readiness and technology integration are likely to define both the pace and the standards of the offshore energy transition toward a low-carbon future.
The offshore segment is at the forefront of advancing low-carbon technologies.
Each conversion tells a story of collaboration; shipyards integrating regasification systems, operators optimising hybrid power, and class societies validating every step for safety and compliance.
Early movers in regulatory readiness and greater technology integration will define the pace and the standards of the offshore energy transition towards a low-carbon future.
